Created through dark experiments on the poor and enslaved the Contra-Paladin is someone who works and(or) devotes their being to an evil deity or themselves through the madness gained upon completion of said experiments.

Villains at heart but they may put on a polite and mild-mannered facade, although their intents remain the same. Much like your average paladin can range from a beacon of hope to a tool of holy wrath, your average contra-paladin may lie through his teeth, and paint himself a noble hero, or they may be the darkest most twisted husks of knights one could imagine.

Create their own form of divinity from the trail of blood they leave behind as well as the power of self-suggestion gained as one of the ways to uphold the sanity they have remaining.
